I am Prof. Alan Chang. Actually, I'm not a professor yet, but hopefully I will be some day! Currently, I am a Ph.D. student and lecturer in the math department. My advisor is Marianna Csörnyei. I started at the University of Chicago in fall 2014. Before coming to Chicago, I was an undergraduate at Princeton.

On this page, you'll find some things that I've been working on. Alternatively, you can just ask my Princeton roommate Minh-Tam about me. I am not so good at making web pages look nice, but Umang is very skilled and helped me a lot!

Notes for lectures/talks

Gauss circle problem: part 1, part 2, and outline - I have given several talks on the 2/3 bound on the Gauss circle problem: (1) In spring 2013, in Elias Stein's Topics in Harmonic Analysis junior seminar. (2) In April 2014, for the Princeton math department's graduate student seminar. (3) In January 2015, for the UChicago math department pizza seminar.

Combinatorial Game Theory - I was a counselor at PROMYS during the summer of 2011. These are notes written to accompany a one-hour talk I gave to high school students. Learn how to win any impartial combinatorial game! (Unfortunately, go is not impartial. Speaking of go, let's play! I have an account on KGS and IGS.)

Teaching

2015-2016, Honors Analysis - I was the teaching assistant for the honors version of the year-long introductory analysis course. The Physical Sciences Division awarded me a teaching prize for my work as a TA. (Thanks to the students for nominating me!!)

Princeton Math Club - I was the president of the math club in 2013. We have a lot of events to make sure that undergraduate math majors (and math enthusiasts) have a great time at Princeton: colloquia, social nights, meet-your-professor lunches, etc.

Mercer County Math Circle - I co-founded this math circle in fall 2013. The math circle meets biweekly at the Princeton Public Library, next to campus. It aims to bring the university and the community together through mathematics. We try to provide fun mathematical activities for students at various levels.

Princeton Splash - In 2012, I founded Princeton Splash, which runs a day-long event where high school students come onto campus to take a number of classes created and taught by Princeton students. Our goal is to support local high schools with non-traditional forms of education and foster a love of learning in the community. In our first Splash (2013), we attracted over 180 high school students and 80 student volunteers. The courses covered a wide array of interests including "Conceptual Quantum Mechanics," "Improv Comedy with Quipfire!", and "The Chemistry of Chocolate."

Learn2cube.com - Learn how to solve the Rubik's cube with my website. I made it back in 7th grade (2004), and have been updating it since then. Here's a video of me in 2017 solving the cube in 12 seconds. (If you see Billy around in the math department, tell him to practice more to improve his speed.)
